These glowing metal cylinders are often gold- or silver-plated and decorated with tiny, glowing arcane symbols. These cores are primarily used to provide life-giving power to an automaton, but an automaton core can also be harvested from an automaton’s body and used to enhance spellcasting (see page 21 for details). A spellcaster holding an automaton core treats her caster level as 4 higher for all purposes.
The innate power of an automaton core depends on the CR of the automaton from which it was extracted: it contains 1 spell point per CR. As a swift action, a spellcaster can expend a number of spell points from the automaton core to cast a spell she has prepared without expending that spell or spell slot. The number of spell points required to use this ability is equal to twice the level of the spell cast. Once all of the automaton core’s spell points are expended, the automaton core can no longer power an automaton. There are currently no known methods to restore an automaton core.
An automaton core can also be used to offset the cost of building a construct. When it is included in the process of crafting a construct, an automaton core offsets an amount of the construction cost equal to 2,500 gp per spell point. A core used in this manner is still removable following the normal rules for removing an automaton core.
Automatons covet these cores, as they can use a core to reactivate automaton allies whose cores have failed, or whose cores have been stolen. Automatons have been known to ruthlessly hunt down and kill creatures who carry these items.
An automaton core can be destroyed only by placing it in a ritual circle where it is surrounded by six other automaton cores. These surrounding cores must then expend an amount of spell points equal to the remaining points in the central core.
This overloads the central core, destroying it forever.
